This thing can help you trim trees. It works. A few pointers. Connecting all the shafts together isn't that effective. About 4 is the sweet spot. At 5 or more, there is so much flex in the shaft that very little force can be applied to actually cut. Second, I did not realize the fiberglass would actually shed, like fiberglass insulation does. It may be an issue for some. I got several small fiberglass splinters. I had to use a neighbors 5x magnifier to find the splinters in my thumb. They were not wood fibers, but near clear glass fibers. Make sure to where eye, hands, and possible full body clothing. Will have to hire a crew to finish my job.
